Title: Electronic bordering system
Inventor: BERGVALL BENGT ALLAN
IPC: G05D1/02
Filed: 1998-09-15
Abstract: An electronic bordering system (1) for a working tool (2), in which a border cable (3), i.e. an electric cable, is placed above, under or on ground or floor, so that it separates an inner area (4) within the border cable (3) from an outer area (5). The working tool is preferably intended for attendance of ground or floor, such as grass-cutting, vacuum-cleaning, etc. A signal generator (6) feeds the border cable with current, whose magnetic field (7) affects at least one sensing unit (8) located on the working tool, so that the sensing unit emits signals (9) to a control unit (10), which in cooperation with an engine control (11), or a signal system for a driver, and at least one driving source (12, 13) directs the tool's movement in order to prevent it from remoting from the inner area. The signal generator feeds the border cable with current containing at least two alternating-current components (14, 15) of different frequency, and the components are lying in a known relation of time to each other. Thereby the control unit can evaluate the difference in the signals (9) caused by the magnetic field's different directions in the inner area (4) and the outer area (5), and the control unit can emit an area signal (16), which mainly takes up one of two states depending on the position of the sensing unit in relation to the border cable, i.e. an outer area state (17) or an inner area state (18).

Patent CA-2311663-A1 (CA)
Inventor: STERN DAVID LAWRENCE
IPC: B01D53/77
Filed: 1998-11-06
Abstract: This invention describes a process for the scrubbing of sulfur oxides (2) from the effluent of conventional wet lime/limestone sulfur oxides reduction processes (3) in coal or oil fired plants (1). The sulfur oxides are oxidatively sorbed onto solid sorbents (4) such as magnesium aluminate spinel. Reduction with the appropriate reducing gases (such as hydrogen) regenerates the solid sorbent (5), which also yields a process stream containing sulfur oxides. The sulfur oxides containing stream (6) can be re-fed to the front end of the coal or oil fired plants (1), with the sulfur oxides thus produced ultimately being removed in the conventional wet scrubbing technology (3). This process may allow for the use of high sulfur fuels.

Title: Method for operating a discharge lamp
Inventor: DOELL GERHARD
IPC: H01J61/92
Filed: 2000-06-22
Abstract: The invention relates to an operating method, in particular a dimming method for a discharge lamp. In order to set the maximum brightness, two outer electrodes (5,6), for example, are used to generate in the discharge lamp a dielectrically impeded discharge which, through the formation of xenon excimers, emits UV radiation which is converted into light with the aid of fluorescent materials (2). In order to permit intense dimming of the discharge lamp, two cold cathodes (3, 4) are used to generate a xenon low-pressure discharge emitting UV beams, and the dielectrically impeded discharge is switched off. Both types of discharge are preferably excited by means of high-voltage pulses which are generated by an operating unit (7). Dimming is preferably performed by blanking pulse trains.

Patent CA-2313630-A1 (CA)
Inventor: DE COURSSOU THIERRY BRUNET
IPC: G06K7/08
Filed: 2000-07-05
Abstract: A sensor and a method for determining the state of conductive ink patterns applied to scratchable latex layers of instant-win tickets and other documents having scratchable latex layers affixed thereon. The device and method are based upon the generation of a radio frequency field across the conductive ink patterns on the document, using an array of miniature transmission RF antennas and reception antennas, and the detection of the induced radio frequency signal. The presence, absence or state of the conductive ink patterns subjected to the RF field affects and changes the signal received on the receiving antennas. The signal received on the receiving antennas is conditioned and processed, so as to extract therefrom information relative to the state of the conductive ink patterns.  This non-contact method does not damage the latex layer when the ticket or document is advanced at high speed through the sensor and is suitable for integration into high-speed optical scanners.

Title: Device and method for preventing ion source gases from entering reaction/collision cells in mass spectrometry
Inventor: TANNER SCOTT D
IPC: H01J49/06
Filed: 2000-08-30
Abstract: A mass spectrometer has an ion source for producing sample ions. The ions pass through an ion interface, to a reaction/collision cell section. An ion-neutral decoupling device is provided between the ion interface and the reaction/collision cell section, to provide substantial separation between ions and neutral particles, whereby only ions pass on to the reaction/collision cell section. The supersonic jet entering the spectrometer can have sufficient energy to cause the plasma gases, such as argon, to overcome the pressure differential between the reaction/collision cell and an upstream section of the spectrometer so as to penetrate into the reaction/collision cell; the decoupling device prevents this. The decoupling device can have offset apertures provided by plates or rods or other comparable arrangements, or can comprise a quadrupolar electrostatic deflector, an electrostatic sector deflector or a magnetic sector deflector.
